Gearheads and greasemonkeys (the kind that aren't into custom JavaScript/CSS tweaking) will probably dig the sponsored themes crafted by Ferrari, Ducati, Infiniti, and Porsche. Those looking to spruce up their desktop with frames from around the world can grab international themes from more countries than originally included in Windows 7's Release Candidate packages.

The full-fledged themes are specific downloads for Windows 7 users, but anyone can grab the wallpapers from Windows 7's Personalization Gallery for their system. Got another source for your newly-installed system's theme? Tell us about it in the comments.
